To alt 107mm it may concern.'

Be it known that I, IVILLIAM Il. JON-ns, a citizen of the United States, residing at Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Heating Systems, of which the tollowing is a speci tication.

My invention relates to heating systems employing either steam or hot water as the heating medium and consists in a system capable oit such control that a portion oitl its radiating surface, such for instance as its pipes, may be cut out of service without interrupting the operation oit the remainder of the radiating pipes and without rendering the same liable to explosion or injury in any respect, with the resultthat the temperature may be readily controlled and the system kept in continual operation.

My new system ot' heating finds particular advantage and utility on .railway cars, especially sleeping cars, where it is desirable to materially reduce the temperature at night without cutting out the entire heating system of the car. In the present instance, I accomplish this result by providing in the piping of the heating system of the car one or more valve mechanisms which, under normal conditions, permit of the usual operation of the system as a whole by allowing the heating medium, steam or water, to circulate through all of the heat radiating pipes but which, when operated, are arranged to short circuit them, so to speak, and thereby render some of them inactive.

According to my invention, by the provision of two valve mechanisms, the parts of the heating system on both sides of the body or main portion of an ordinary sleeping car may be separately regulated in the manner already explained and by the provision of additional valve mechanisms such control may be extended to the parts oit. the heating system in the smoking room, drawing room and state rooms of such a car. Moreover, my heating system may be installed to advantage in compartment ears and combined compartment and observation cars, with the result that the temperature of each compartment and of the observation section may be independently controlled.

For convenience in description, I have illustrated my invention as applied to railway cars and will proceed to describe the same in connection therewith. Moreover, while the heating medium may be either steam or hot water, l will refer to the same as hot water which, in the usual heating systems ol railway cars is heated indirectly by the steam in a train pipe :from the locomotive, although it may be heated by a' heater located in the car.

ln the drawings lligurc l is a View illustrailing two of my valve mechanisms as embodied in the compartment car heating' tem and showing one of the valve mechanisms in section; Fig. 2 another section ot the valve similar to that in Fig. l but on a larger scale; and Fig. 53 a cross section taken on the irregular line ll---floi. Fig. 2.

The same .reference characters indicate corresponding parts in the several views oiE the drawings.

A suitable arrangement oi piping :t'or embodying my invention shown in Fig. l of the drawings, which represents .'lfour pipes connected by return bends, such as would be adapted to heat a single compartment ot an ordinary sleeping car. The hot water passes downwardly lrom the flow pipe l successively through the pipes 2, 3 and -l-, and

thence to the right and upwardly to a simi-- lar pipe 2 of another set ol pipes in an adjoining compartment, whence in similar manner it passes dmvuwardly through pipes 3 and 1-, and so on, :for as many sets of pipes and compartments as may be included in the system. In order to provide for reducing the heating ellect in any single compartment or other portion oil the car, I have provided in each compartment a valve mechanism 7 so constructed and located with respect to the pipes that it will practically short circuit the pipes 2 and 3 and cause the water to flow from the pipe 4lv o'l' one compartment to the corresponding pipe 4: oit the next adjacent compartment and so on. In this manner, one halt olf the heating surface oi' cach compartment may be cut out oi service without interrupting the working of the system. It will loe understood that the ends of the car may, lf desired, be likewise provided with the valve mechanism 7 with similar results.

The valve mechanism, as herein shown, comprises a easing having connections with the pipes 2 and 3, and interposed in the length thereof and near their coupled or connected ends and opposite their return bends, leaving, however, a portion of said pipes 2 and 3 always in the line of circulation and never cut ott' by the valve mechaa rock shaft i 13.

nism as hereinafter made apparent. The casing is provided with a chamber or passage S normally connecting the two portions of pipe 2 and permitting the hot water to circulate in the usual manner already described, and the same is also provided with a chamber or passage 9 connecting the two portions of pipe 3 and adapted to communicate with the other chamber through a port 10. `Within the chamber S is arranged a valve 11 carried on the end of an arm 12 which is itself mounted on the inner end of through one side of the valve casing and through a packing 1li and its packing nut or gland 15 and is provided at its outer end with a suitable operating handle 16. The valve, which is arranged to rock in an arc of 900, has seating faces on its opposite sides and in one position is adapted to fit upon the seat 17 as shown in Fig. 2, thereby interrupting the circulation through the pipe 2 and opening communication between the left hand ends of the pipes 2 and 3, and in the other position to iit upon the seat 18 at port 10 thereby closing said port and causing the water to circulate in the usual or normal manner throughout the full lengths of pipes 2 and 3. By preference, l provide the chamber 9 immediately below port 10 with a depending curved iiange or deflector 19 pointing in the direction of circulation for deflecting the current when the port 10 is open as shown.

According to my construction the valve mechanism serves to cut out the main portions of the pipes 2 and 3 from the circulating system when the valve is in the position shown in Fig. 1, for instance, but it does not cut off communication thereof with the system as the valve merely-closes the front end of this portion of the pipe 2, leaving the `corresponding end of the pipe 3 open to the main circulating system. In other words the valve mechanism is arranged to cut out the main portions of pipes 2 and 8 from the line of circulation of the hot water or heating fluid without cutting oi'f their communication with the heating system, the circulation being in a general downward direction. As a result of this construction, the' water is not trapped or confined in these portions of pipes 2 and 3 when they are cut off from the line of circulation as described and consequently the expansion of the water is provided for and prevented from breaking the pipes or opening the joints and thereby causing leakage thereat. Y

lt will be evident that by means of the valve mechanism, the pipes 2 and 3, practically to their full extent, can be cut out of service without stopping the circulation of This rock shaft extendsv 4,tem and the heating pipes 2 and 3 communicating therewith, of a valve mechanism for cutting said heating pipes out of service .comprising a casing having through pas- :sages communicating :pipes and said system, .communication between said passages, double seating valve normally closing said .port to cause circulation through said pipes the system which will continue through the hot water pipe 1 and the return pipe 4. In this manner the amount of heating or radiating surface is reduced practically one half. The compartments being provided with their own valve mechanisms can thus be in dependent-ly regulated as to temperature, inasmuch as each of the valve mechanisms is operable separately and regardless of the operation or non-operation of any o f the others.
